GEORGE W. PRENTIGE, OF PROVIDENCE, RHODE ISLAND.

BUTTON-FASTENER.

SPECIFICATION forming part of Letters Patent No. 315,065, dated April'7, 1885.

Application filed December 31, 1884. No model.)

To all whom it may concern:

Be it known that I, GEORGE W. PRENTIOE, a citizen of the United States,residing at Providence, in the county of Providence and State of RhodeIsland, have invented certain new and useful Improvement-s in Button-Fasteners; and I do declare the following to be a full, clear, and exactdescription of the invention, such as will enable others skilled in theart to which it appertains to make and use the same, reference being hadto the ac;

companying drawings, and to the letters and figures of reference markedthereon, which form a part of this specification.

My present invention relates to button-fasteners of the class known asprong-fasteners, composed of a plate having prongs integral therewith,one of said prongs adapted to be bent to form a loop, and an additionalplate or bearing, both the said plates to be secured to fabric by meansof the prongs, which are caused to penetrate the same and be clinched bymeans of a suitable setting-in-' strument.

In the accompanying drawings, Figure 1 represents the blank from whichmy improved fastener is formed. Fig. 2 is a side elevation of myimproved fastener. Fig. 3 repre sents the fastener with button asattached to fabric.

Similar letters of reference indicate like parts in the several figures.v

In carrying out my invention I first cut the blank A from sheet metal insubstantially the form shown in Fig. 1, consisting of the plate (0,provided with three parallel integral prongs, b b and c, the longer andsingle prong, c, constituting the button-carrying prong, being oppositeand in line with the space between the prongs b. The prongs are allsubsequently bent downward at right angles to the plate a, the singleprong a being bent horizontally near its junction with the said plate toform the elongated loop a for the reception of the eye-shank of abutton, the lower portion of said loop forming a table, a the remainderof the prong c projecting downward from the inner end of said table, asfully shown in Fig. 2. The end of the prongs are sharpened to readilypenetrate the fabric in attachment.

In the operation of attaching buttons to fabric by means of my improvedfastener, the eye-shank of a button is passed over the prong cinto theelongated loop a. The prongs of the fastener are then inserted throughthe fabric and clinched on the under surface, the prongs being clinchedtoward the elongated loop a, as fully shown in Fig. 3.

By means of my improvement I am enabled to provide a strong and durablefastener for eyeshank buttons. The double prongs are clinched under theplate of the fastenenwith their points concealed in the fabric, whilethe single prong is bent forward and clinched in the same direction,firmly clamping the fabric against the base of the elongated loop,thereby greatly increasing the holding capacity of the fastener, andalso lessening the liability of the single prong becoming detached fromthe fabric.

I have shown and described a fastener provided with threeattaching-prongs. The number may be varied, if desired. The same resultwill also be accomplished if the fastener is made of wire or out toform, as shown, from sheet metal, ready for use when so cut.

Having described my invention, I claim 1. A button-fastener composed ofa table provided with attaching-pron gs integral therewith, one of saidprongs being bent horizontally into an elongated loop for the receptionof the eye-shank of a button, the lower portion of said loop forming atable provided at its inner end with -a penetrating attaching prong, theprongs of the fastener adapted to be passed through a fabric and beclinched in the same direction, substantially as and for the purpose setforth.

2. The one-piece metallic button-fastener A, consisting of the plate aand the parallel prongs b b and c, the prong c constituting thebutton-carrying prong and bent horizontally into an elongated loop, a,forming the table a, all as shown and described, and for the purpose setforth.

In testimony whereof I afiix my signature in presence of two witnesses.
